■
Current Position - Requests weather information within the
specified Coverage Radius of the aircraft position, regardless
of flight plan.
●
Coverage Radius (NM) - Select 50, 100, 200, 300 or 400
nautical mile radius around the aircraft or flight plan as the display
area for depicting weather.
●
Datalink Radar Resolution - Select High, Medium, or Low
Datalink Radar resolution. The “Low” setting uses the least
message units and most likely will provide the fastest updates.
Increasing this setting provides improved Datalink Radar details,
but, in turn, increasing the message units can decrease the
actual update rate.
●
Request Interval - Select the frequency of weather updates.
The update frequency varies per region depending on how often
weather data is updated. Also, changing satellite and network
conditions can affect the update rate. The intervals are:
■ Maximum Rate - Weather data is updated as soon as
updated weather is available.
■
High Rate - Data is updated typically every 10 minutes (up to
6 updates per hour).
■
Medium Rate - Data is updated typically every 20 minutes
(up to 3 updates per hour).
■
Low Rate - Data is updated typically once per hour.
Note:
Satellite visibility and network traffic may cause an additional
missed update.
Note:
Faster rates for request intervals consume significantly more
message units.
Weather Types - The Weather Type fields enable you to select the
type of weather data to receive. To enable a weather type, check the
checkbox for that weather. The following weather data subscriptions
can be enabled or disabled:
